• Spanning tree mode – Specifies the type of spanning tree used on this switch:
- STP: Spanning Tree Protocol (IEEE 802.1D)
- RSTP: Rapid Spanning Tree (IEEE 802.1w)
• Root Hello Time – Interval (in seconds) at which this device transmits a
configuration message.
• Root Maximum Age – The maximum time (in seconds) this device can wait
without receiving a configuration message before attempting to reconfigure. All
device ports (except for designated ports) should receive configuration messages
at regular intervals. If the root port ages out STA information (provided in the last
configuration message), a new root port is selected from among the device ports
attached to the network. (References to “ports” in this section means “interfaces,”
which includes both ports and trunks.)
• Root Forward Delay – The maximum time (in seconds) this device will wait
beforechanging states (i.e., discarding to learning to forwarding). This delay is
requiredbecause every device must receive information about topology changes
before itstarts to forward frames. In addition, each port needs time to listen for
conflicting information that would make it return to a discarding state; otherwise

• Priority – Bridge priority is used in selecting the root device, root port, and
designated port. The device with the highest priority becomes the STA root device.
However, if all devices have the same priority, the device with the lowest MAC
address will then become the root device.

consecutive RSTP BPDUs.
• Path Cost Method – The path cost is used to determine the best path between
devices. The path cost method is used to determine the range of values that can
be assigned to each interface.
